One problem related to diesel engine has been reported for the 2019 Ford F-250. The most recently reported issues are listed below.
At 23,000 miles my truck started shaking violently while traveling down the freeway at 60 miles per hour. It was shaking so violently that I lost control of steering completely. The only way to stop the shaking was to slam on my brakes in traffic before I hit the highway divider. My research tells me it is the death wobble. It shook something loose in my diesel engine, because the engine is knocking now. On the way home I stayed on the service road and kept the truck under 45 miles per hour. It happened again at 45 miles per hour, so I started driving at 30mph to try and make it home. It happened 3 more times at 30 mph. I discovered that it starts shaking when I go over the slightest bump in the road. It shakes so violently it throws me around in the seat and I cannot hang onto the steering wheel. I have to come to a complete stop when it happens before it will stop shaking. Once I come to a complete stop I can start accelerating again without it shaking. As soon as I drive over a bump in the road the shaking starts again. It is extremely dangerous, because I loose total control of the truck, and I am a 6 foot muscular man. No matter how hard I try I cannot hang onto the steering wheel. Now I understand why they call it the death wobble. It is very dangerous.
